A simple script
 

I am trying to develop a script to do the following steps in MUI (although working in MUI is not a must and I suspect mixing code with non MUI scripts is my problem):

1. copy 3 files to system32 folder.
2. Add keys to the registry
3. reboot
4. run a VB script
5. detect java runtime version
6. update path and class path
7. detect Acrobat version and update the registry keys for it.

All you experinced users out there, is this doable in NSIS?
Can you kindly help me with 1, 3 and 7?

Although powerful, this program is not so straight forward and the tutorials/help leave out a lot.

1. File or CopyFiles & system dir.
3. Reboot.
7. Wiki

Well...seems that must of your awnsers are in the tutorials/help site :)
